In SMT patch production, lots of clients will purchase their elements to locate SMT makers for batch handling, so what problems should be paid attention to when buying parts? Noting: Each plan ought to include the very same part number, plan, and worth info as in the BOM. If possible, it is best to place a code name on each package. If there is any distinction from the details in the BOM, you must contact us beforehand to deal with the BOM.
Components Excess: Resistors, Capacitors, and diodes (0603, 0805, 1206, 2225, SOT, SOD, MELF – plans) need a minimum of 50 items and should surpass the requested amount by 30 pieces. (Example: Setting up Quantity 40 items – we will require 70 pieces – this meets our minimum of 50 pieces plus the Assembly Amount 30 pieces). Resistors, Capacitors, and diodes (0201, 0402, Mini Melf, Micro bundles) require a minimum of 100 items and need to surpass the asked for amount by 50 pieces. (Instance: Setting up Quantity 80 items – we need 130 pieces – this fulfills our minimum of 100 items plus the 50 items extra of the Setting up Quantity). Little excess (1-5 pieces based upon the overall Setting up Amount) is required for expensive parts such as IC, BGA, QFP, Connectors, and so on, which will make certain smooth SMT assembly and on-time distribution of your put together boards.
Packaging: SMT elements that are not provided in reel type ought to be placed on a continuous strip of tape. If you require to construct the same SMT components on different boards, do not cut them right into strips, place them on a continuous tape or reel. Elements on tubes or trays are also ideal for setting up.
